昆虫介导的授粉服务的缺陷破坏生态系统的生物多样性和功能，人类营养和经济福利。全球传粉媒介的供应继续减少，而依赖传粉的作物的产量增加。使用公开的价格和生产数据和现有的授粉领域的研究，我们量化的经济依赖，美国作物在县级昆虫介导的授粉服务，并更新现有的系数样本作物的昆虫依赖。2012年，依赖授粉服务的经济价值总计340亿美元。20%的美国县产生了80%的总经济价值归因于昆虫授粉。我们编制了县级数据，并考虑了依赖于昆虫介导的授粉的经济价值、特定地区饲料适用性和美国景观内特定作物农业区域之间的空间关系。我们确定了脆弱的，高度依赖的地区，野生传粉者的栖息地已经减少。这些结果有助于为未来保护和支持管理和野生传粉者种群的努力提供信息，以确保关键农作物的可持续生产。
Deficits in insect-mediated pollination service undermine ecosystem biodiversity and function, human nutrition, and economic welfare. Global pollinator supply continues to decline, while production of pollination-dependent crops increases. Using publicly available price and production data and existing pollination field studies, we quantify economic dependence of United States crops on insect-mediated pollination service at the county level and update existing coefficients of insect dependence of sample crops when possible. Economic value dependent on pollination service totals 34.0 billion USD in 2012. Twenty percent of US counties produce 80% of total economic value attributable to insect pollinators. We compile county-level data and consider the spatial relationship between economic value dependent on insect-mediated pollination, region-specific forage suitability, and crop-specific agricultural areas within US landscapes. We identify vulnerable, highly dependent areas where habitat for wild pollinators has been reduced. These results can help inform future efforts to conserve and bolster managed and wild pollinator populations to ensure sustainable production of key agricultural crops.
